APPARATUS FOR COVERING LAClNG-HOOKS.

SPECIFICATION forming part of Letters Patent No. 569,969, dated October20, 1896.

I Application filed January 30, 1896. Serial No. 577,405. (No model.)

To a whom it may concern.-

Be it known that I, ELEAZER KEMPSHALL, of Newton, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Apparatus for Covering Lacing-Hooks, of which thefollowing is a specification.

This invention relates to means used for applying a covering of plasticmaterial,such as pyroxylin composition, to metallic articles, such asthe heads of lacing-hooks; and it has for its object to provide a simpleand convenient apparatus of this class whereby the covering operationmay be rapidly and efficiently performed.

The invention consists in the improvements which I will now proceed todescribe and claim.

Of the accompanying drawings, forming a part of this specification,Figure 1 .represents a top plan view of a portion of the supportingplate or base forming apart of my improved apparatus. Figs. 2, 3, and atrepresent sectional views on the line 2 2 of Fig. 1, on an enlargedscale, showing the parts of the apparatus at dilferent stages of theoperation. Fig. 4: represents a perspective view of the holder for thearticle to be covered. Figs. 5, 6, and 7 are top views, each showing aportion of the base-plate and a lacing- Fig. 8 represents a view similarto Fig. 4, showing a surface formed to mold the covering on the neck ofa lacing-hook. Figs. 9 and 10 represent sectional views showing adiiferent mechanical construction embodying my invention.

The same letters of reference indicate the same parts in all thefigures.

'In'the drawings, referring first to Figs. 1 to -8, inclusive, arepresents a base-plate, in which is formed a socket a, which is ofsubstantially cylindrical form. In this socket is fitted-to move in andout a holder 1), which is adapted to hold an article to be covered,

the said article being in this case a lacinghook c. The holder b has anouter face I),

which, when the holder is at the bottom of the socket, is within theouter end of the socket, as shown inFigs. 3 and 4, the socket extendingabove or outsideof the face band plate a, said die having a cutting edgee and being formed to press the blank cl down upon the head of thelacing-hook held by the holder 1), cutting off the surplus marginalportion of said blank and forcing a portion of its material through anorifice or orifices in the head of thelacing-hook and against theface 1) below said head, thus forming a molded cover 0, which isinterlocked with or anchored to the head of the lacing-hook, as shown inFig. 4, the face I) constituting a bottom die which cooperates with thetop die 6.

- The holder 19 is movable in the socket Ct to elevate the face I) andthe lacing-hook thereon above the base-plate a, as shown in Fig. 2, forthe ready removal of the covered hook and the application to the holderof an uncovered hook. The holder 1), as here shown, has a cavity 11below the top face I), said cavity being formed to receive the shankportion of the lacing-hook. In one edge of the top face 6 is formed arecess b communicating with the cavity 19 and formed to receive the neckwhich connects the head and shank of the lacinghook.

I prefer to form an enlargement a at the upper end of the socket a, saidenlargement being above the top face b of the holder 1) when the latteris in its lowest position in the socket, the bottom a of saidenlargement being flush with and constituting auextension of the topfaceb of the holder, said extension being arranged to cooperate with aportion of the cutting edge e of the die e in forming the margin of thecover 0 at and near the neck of the lacing-hook.

The holder 6 maybe guided in its movements and prevented from rotatingin the socket by anysu'itable fmeans, preferably a key or spline 'g,inse pain a cavity formed for I l its receptionin the-wall of the socketa and projecting into a groove gfi formed in the holder b, the inner endof said groove and the lower end of the key g forming stops which limitthe outward movement of the holder, as shown in Fig. 2.

The operation is as follows: The holder 7) being raised, the lacing-hookis placed upon it, as shown in Fig. 2. The holder is then depressed,carrying the hook into the socket, and a blank d of pyroxylincomposition is placed in the mouth of the socket above the holder andresting on the head of the hook, as shown in Fig. 3. The die e is thendepressed, as shown in Fig. 4, and molds the material of the blank inthe manner described and shown, the holder, base-plate, and die beingsuitably heated to soften the blank and makeit sufficiently plastic toassume the form shown in Fig. 4. After the formation of the cover, theholder 1) is raised, thus removing the covered hook from the socket andpermitting its ready removal from the holder.

The base-plate a in practice will contain a large number of sockets andholders, and said plate is preferably portable or movable, so that itmay be set up edgewise while the uncovered hooks are being applied, andmay then be placed horizontally upon a suitable supporting-bed while thedies 6, which are assembled in a corresponding number on a suitable dieplate or holder e, are being brought down to mold the covers.

The holder 1) may be simultaneously raised to eject the covered hooksfrom the die-plate by placing the die-plate upon a series of pins orspindles i, affixed to a suitable supporting base or plate and arrangedto coincide with orifices 1., formed in the bottom of the baseplate aand communicating with the sockets a, the base-plate a being removedfrom the bed which supports it during the molding operation abovedescribed and placed upon the pins 11, which support the holders intheir elevated position during the removal and application of the hooks.Any other suitable means may be used for simultaneously raising ordisplacing the holders without departin g from the spirit of myinvention.

I do not limit myself to the provision of blank-receiving cavities inthe socketsat the outer ends of the holders, as the blanks may be cut bythe dies from sheets placed between the dies and bed, or the blanks, ifpreviously formed, may be held in any other suitable way.

It is obvious that the essential features of my invention, namely, abase-plate havinga socket and a holder formed to be contained in thesocket and to hold the article to be coated therein, the holder andsocketed plate being relatively movable, so that the holder and aportion of the article engaged therewith are securely held within thesocket when the said parts are in their operative position and areremovable from the socket to permit the ready application and removal ofthe article, may be used in apparatus for covering other articlesbesides l'acing-hooks, the form of the holder and die and, if necessary,of the socket in the base-plate being modified to suit the form-of thearticle.

By my improvement I am enabled to form a cover upon a lacing-hook orother like article without forming a mark across the top surface of thecover, as is necessarily the case when said top surface is formed by twohalfdies the joint of which extends across said surface.

In Fig. 8 I show a cavity a formed in the wall of the socket a adjacentto the recess b in the holder 1), said cavity being formed to mold anextension of the cover on the outer side of the neck of the lacing-hook.

In Figs. 9 and 10 I show the holder as a stud or projection 12 formed ona fixed bed or plate Z2 the corresponding socket a being formed in aremovable plate 0. In this case the holder is exposed for theapplication and removal of the article by removing the plate 0. theholder being covered and the article confined by placing the plate (0 onthe plate Z2 I claim- 1.
